Methylcobalamin acts as an essential cofactor in two primary enzyme reactions crucial for human metabolism: Homocysteine to Methionine Conversion: Methylcobalamin is required by the enzyme methionine synthase
Other biosynthesis As described earlier, glutamine is required for two steps in purine biosynthesis, whereas aspartate, which acquires its nitrogen from glutamate, is required for a step in purine biosynthesis and a step in pyrimidine biosynthesis
